CalculateBalance now works correctly: if confirmations is 0, all UTXOs
will be used for the balance. Otherwise, unconfirmed UTXOs will be
exclused. 1 confirmation will allow the UTXO height and current block
height to be equal. Even though the difference is zero, the
transaction including the UTXO has been mined into one block.
This change also remove extraneous account balance notifications for
connected and disconnected blocks.
Any and all resending should be handled directly by btcd, and btcd
ignores any duplicate transactions when adding to mempool anyways. A
set of unmined txs is still kept and send to btcd in case of btcd
restarting and losing wallet transactions from its mempool.
In case of a btcd restart, it is necessary to send unmined
transactions back to btcd so they can be added to the tx mempool.
btcd can make a best-try effort, but It is ultimately btcwallet's
responsibility that transactions appear in blocks even if btcd is
restarted.
This copies the functionality of btcd for choosing the ports for the
HTTP client (for btcd) and server (for frontends). On testnet, the
following ports are used as default:
- btcd: 18334
- frontends: 18332
When running with the (currently disabled) --mainnet flag, btcwallet
will choose the following ports by default:
- btcd: 8334
- frontends: 8332
Both ports can be overridden no matter the chosen network using the -b
and -p flags.
We need to notify frontends of notifications for every account
(wallet), not just the "current" opened account, since wallet will
need to have multiple wallets open at the same time. Frontends will
have to filter notifications to show only details of only one account
if they need to display just one account at a time.
As of this commit, account balances and lock state notifications are
using this per-account notification scheme.
Use on mainnet is not recommended until extensive testing has been
done, and should be done at your own risk. Run btcwallet with
--mainnet to operate on main Bitcoin network.
This is a big change that also many general fixes to problems found
when creating transactions. In particular the Utxo and Tx formats and
serialization functions were updated with additional information that
would be necessary for rolling back old utxo and tx data data after
btcd chain switches. This change also implements the json methods
'sendfrom' and 'sendmany' to create a new transaction based on a
frontend request.
Transactions are currently not sent to btcd since the tx relay code is
not finished yet, so a temporary error is returned back to frontends
who try to send new transactions.
btcd was changed to send the block hash for new block notifications as
a big endian string, so type assert as a string and convert to a
btcwire.ShaHash.
Each wallet needs its own handler running and listening to replies
from btcd, so that wallet can be synced to disk with the new tx or
utxo information. Another rounter to map from addresses to wallets
could have been written, but we'll use the JSON Id router message
router instead.
